| // Package fipsonly restricts all TLS configuration to FIPS-approved settings. | |
| // | |
| // The effect is triggered by importing the package anywhere in a program, as in: | |
| // | |
| // import _ "crypto/tls/fipsonly" | |
| // | |
| // This package only exists when using Go compiled with GOEXPERIMENT=boringcrypto. | |
| package fipsonly | |
| // This functionality is provided as a side effect of an import to make | |
| // it trivial to add to an existing program. It requires only a single line | |
| // added to an existing source file, or it can be done by adding a whole | |
| // new source file and not modifying any existing source files. | |
